2.   This Bond is issued and the Agreement was made and entered into under and pursuant to the constitution and laws of the State
of Florida, particularly Parts II and III of Chapter 159, Florida Statutes, as amended (the Act), and under and pursuant to resolutions duly adopted by the Authority.

3.   Terms which are used herein as defined terms and which are not otherwise defined shall have the meanings assigned to them in the Agreement.

4.   Copies of the Agreement
are on file at the principal corporate trust office of the Trustee. Reference is hereby made to the Agreement for the provisions, among others, with respect to the custody and application of the proceeds of Bonds issued under the Agreement, the

which the Bonds are or may be issued, the conditions under which after an Event of Default the principal amount of this Bond may be declared due and payable, the rights, duties and obligations of the Authority and of the Trustee and the rights of
the holders of the Bonds.

5.   The Agreement also prescribes the manner in which it may be discharged and after which the Bonds shall no longer be secured by or entitled to the benefits of the

7.   This Bond shall bear
interest from and including the Interest Payment Date next preceding the date of authentication hereof, or, if such date of authentication shall be an Interest Payment Date to which interest on this Bond has been paid in full or duly provided for,
this Bond shall bear interest from its date of authentication, or, if no interest has been paid or duly provided for hereon, this Bond shall bear interest from the date of initial authentication and delivery of Bonds under the provisions of the
Agreement; provided, however, that if, as shown by the records of the Paying Agent, interest on the Bonds shall be in default, Bonds issued in exchange for Bonds surrendered for registration of transfer or exchange shall bear interest from the last

10.   REDEMPTION PROVISIONS. IN CERTAIN CIRCUMSTANCES SET OUT HEREIN, THIS BOND (OR PORTION HEREOF) IS SUBJECT TO REDEMPTION, IN EACH CASE UPON NOTICE TO THE OWNER HEREOF AS OF A DATE PRIOR TO SUCH PURCHASE OR REDEMPTION. IN EACH SUCH EVENT AND UPON DEPOSIT OF THE
REDEMPTION PRICE WITH THE PAYING AGENT ON THE REDEMPTION DATE THIS BOND (OR PORTION HEREOF) SHALL CEASE TO BE DEEMED TO BE OUTSTANDING UNDER THE AGREEMENT, INTEREST HEREON SHALL CEASE TO ACCRUE AS OF THE PURCHASE OR REDEMPTION DATE, AND THE

WITH THE PAYING AGENT BUT ONLY UPON SURRENDER OF THIS BOND TO THE PAYING AGENT.

11.   The Bonds shall be subject to redemption at the
option of the Company in whole or in part at any time on or after October 1, 2012, at a redemption price equal to the principal amount redeemed, plus interest accrued to the redemption date. If this Bond is of a denomination in excess of the minimum
Authorized Denomination, portions of the principal amount in Authorized Denominations may be redeemed. If less than all of the principal amount is to be redeemed, upon surrender of this Bond to the Paying Agent, there will be issued to the
Registered Owner, without charge, a new Bond or Bonds, at the option of the Registered Owner, for the unredeemed principal amount.

12.   In the event that (i) continued operation of the Units
becomes impracticable, uneconomical, or undesirable, (ii) the Units are condemned or taken by eminent domain, or (iii) the Company is prevented from carrying on normal operation by injunction as provided in the Agreement, the Bonds may be redeemed
as a whole on any date selected by the Company, but not less than 45 days after nor more than 180 days after the Company shall have given notice of its exercise of the right to make such prepayment, at the principal amount thereof plus accrued
interest to the redemption date, and without premium.

13.   In the event that the interest on any Bond has been determined to be includable in gross income for federal income tax purposes in
accordance with and as provided in the Agreement due to the failure of the Company to observe any covenant, agreement or representation in the Agreement, the Bonds shall be called for redemption as a whole or in part, on any date selected by the
Company, but not later than 180 days after the date of such determination, at the principal amount thereof plus interest accrued thereon to the date fixed for redemption, and without premium. The Bonds shall be called for redemption in part only if
the interest on the Bonds which remain outstanding following such redemption will, in the opinion of nationally recognized bond counsel, be excluded from gross income for federal tax purposes.

14.   If less than all of the Outstanding Bonds are to be called for redemption, the Bonds (or portions thereof) to be redeemed shall be selected as provided in the Agreement in Authorized Denominations.

15.   The Paying Agent shall give or cause to be given notice of any redemption of this Bond as provided above to the Registered Owner at its address shown on the registration books maintained by the Paying
Agent. A certificate of the Paying Agent shall conclusively establish the mailing of any such notice for all purposes. Notice of redemption having been duly mailed, this Bond, or the portion called for redemption, will become due and payable on the
redemption date at the applicable redemption price and, moneys for the redemption having been deposited with the Paying Agent, from and after the date fixed for redemption, interest on this Bond (or such portion) will no longer accrue. If a portion
of this Bond shall be called for redemption a new Bond or Bonds in principal amount equal to the unredeemed portion hereof will be issued to the Registered Owner upon the surrender hereof.

16.   If any Bonds are not presented for payment at their redemption or maturity date, the Registered Owners thereof shall look only to the moneys set aside for such purpose by the

6

Paying Agent. After one year, such moneys may be paid to the Company, and the holders of such Bonds shall thereafter look only to the Company for payment thereof.

17.   The transfer of this Bond may be registered by the Registered Owner hereof in person or by his attorney or legal representative at the principal corporate trust office of the Registrar, but only in the
manner and subject to the limitations and conditions provided in the Agreement and upon surrender and cancellation of this Bond. Upon any such registration of transfer, the Authority shall execute and the Paying Agent shall authenticate and deliver
in exchange for this Bond a new registered Bond or Bonds, registered in the name of the transferee, of Authorized Denominations, in aggregate principal amount equal to the principal amount of this Bond, of the same series and maturity and bearing
interest at the same rate.

18.   The Registered Owner of this Bond shall have no right to enforce the provisions of the Agreement or to institute action to enforce the covenants therein, or to
take any action with respect to any Event of Default under the Agreement, or to institute, appear in or defend any suit or other proceeding with respect thereto, except as provided in the Agreement.

19.   Modifications, alterations or amendments of the Agreement or of any amendment thereto may be made only to the extent and in the circumstances permitted by the Agreement.

20.   This Bond shall be governed by and construed in accordance with the laws of the State of Florida.

21.   All acts, conditions and things required to happen, exist and be
performed precedent to and in the issuance of this Bond and the execution of the Agreement have happened, exist and have been performed as so required.

22.   The Registered Owner of this Bond, by
acceptance hereof, is deemed to have agreed and consented to the terms and provisions of the Agreement.

23.   The Authority, the Trustee and the Company may treat the Registered Owner as the
absolute owner of this Bond for all purposes, notwithstanding any notice to the contrary.

24.   Neither the members of the Authority nor any person executing this Bond are liable personally hereon
or subject to any personal liability or accountability by reason of the issuance hereof.
